Hei. I just pulled arrow-fx, thinking to raise a PR (or atleast trying to), so I want to build the project from intellij. But I am getting this :

Kotlin: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class arrow.core.computations.EitherEffect, unresolved supertypes: arrow.continuations.Effect

Can anyone help me 🙂

A lot of files don’t compile because computation class are missing, I am guessing because of error above.

Using jdk 1.8, but it has scala dep as well, so I am getting this too :

scalac: '13' is not a valid choice for '-target'

Hey @Satyam Agarwal,
Yes there was a conflict between merging Arrow Core and Arrow Fx.

I raised 3 PRs this morning to fix the build.

https://github.com/arrow-kt/arrow-fx/pull/323
https://github.com/arrow-kt/arrow-incubator/pull/137
https://github.com/arrow-kt/arrow-core/pull/265

I'm not sure about the Scala issues tho

[simon.vergauwen]

This has been merged and is fixed

[Satyam Agarwal]

Awesome. Thanks. I’ll pull.

compiler daemon dies because of memory. I am giving intellij 2 gb. Will increase it to 3 and see.

arrow-benchmark-fx still doesn’t work, but I am able to run tests so thats good enough

[simon.vergauwen]

Arrow Benchmark Fx should be runnable, but it doesn't run by default. What's wrong with it?

[Satyam Agarwal]

I don’t know where jvm13 is coming from, I’ve set java,kotlin,scala compilers to use 1.8

[simon.vergauwen]

That's weird I've never run into that. I also have Scala installed
